description="
A (complex) compression utility based on the LZMA algorithm.

XZ Utils is free general-purpose data compression software with a high
compression ratio.  XZ Utils were written for POSIX-like systems, but
also work on some not-so-POSIX systems.

WARNING:
  The usage of this utility to distribute files or backup your data
IS TOTALLY DISCOURAGED.  Limit its usage to decompression only,
since some maintainers refuse to distribute in a better format.

For more information, see https://lzip.nongnu.org/xz_inadequate.html

It is highly recommended the use of lzip(1) instead of xz(1).
